DS1832S

Supervisors Overview

The DS1832S is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 4.625V and provides an active-high, push-pull reset output. The device features a watchdog timer with a timeout period of 610 ms and includes power-fail detection capabilities. Operating within a supply voltage range up to 5.5V, it maintains accuracy within 2.5% across temperatures from -40°C to +85°C. The component consumes 35 µA during operation and is housed in an SMD/SMT UMAX-8 package.

Supervisors Feature Summary

• Integrated watchdog timer for system fault recovery
• Power-fail detection capability for voltage monitoring
• Active-high push-pull reset output configuration

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Industrial control units

Supervisors Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the manufacturer designation matches current Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor with integrated watchdog functionality is required. Verify that the 4.625V threshold aligns with the monitored rail. Consider the UMAX-8 package constraints for PCB layout and thermal management requirements.

Supervisors Part Context

Part of the EconoReset family designed for cost-sensitive applications. This series provides essential monitoring functions without external components. The DS1832 variant specifically targets microprocessor reset generation with added watchdog protection.

Supervisors Replacement Considerations

Check for direct cross-references in Analog Devices replacement guides. Verify pin compatibility and threshold voltage matching before substitution.
